DescriptionMyelofibrosis (MF) is a rare disorder characterized by hematopoietic abnormalities and fibrosis within the bone marrow.[L40793] The underlying cause of primary MF is unknown, but secondary MF can arise in patients with a history of polycythemia vera or essential thrombocythemia.[L40793] While some patients may remain asymptomatic, typical symptoms of MF arise from abnormalities in blood cell production and may therefore include various cytopenias, infections, splenomegaly, and general systemic symptoms such as fever.[L40793] Approximately 50% of patients with primary MF have a mutation of the _JAK2_ gene, which is also commonly mutated in patients with polycythemia vera or essential thrombocythemia.[L40793] JAK2 signaling is important for hematopoiesis and proper immune functioning,[L40754] and while the precise role it plays in the pathogenesis of MF remains unclear, its clear association with MF has made it a desirable therapeutic target in MF treatment. Pacritinib is an inhibitor of both wild-type and mutant (V617F) JAK2, as well as FMS-like tyrosine kinase 3 (FLT3), which was granted accelerated approval by the FDA in February 2022 for the treatment of both primary and secondary MF in patients with platelet counts < 50 x 10<sup>9</sup>/L.[L40754] It provides a treatment option for patients who have MF with severe thrombocytopenia, which occurs in approximately one-third of MF patients and carries with it a particularly poor prognosis.[L40709]

IndicationPacritinib is indicated for the treatment of adults with intermediate or high-risk primary or secondary (post-polycythemia vera or post-essential thrombocythemia) myelofibrosis with a platelet count below 50 x 10<sup>9</sup>/L.[L40754] This indication is approved under accelerated approval based on spleen volume reduction. Continued approval may be contingent upon verification and description of clinical benefit in confirmatory trials.[L40754]
